This is achieved by customizing 2D circuit-like patterns with an array of conductive strips that can be easily attached to the sensing nodes on the edge of the touchscreen. FlexTouch requires no hardware modification, and is compatible with various conductive materials (copper foil tape, silver nanoparticle ink, ITO frames, and carbon paint), as well as fabrication methods (cutting, coating, and ink-jet printing). Through a series of studies and illustrative examples, we demonstrate that FlexTouch can support long-range touch sensing for up to 4 meters and everyday object presence detection for up to 2 meters. Finally, we show the versatility and feasibility of FlexTouch through applications such as body posture recognition, human-object interaction as well as enhanced fitness training experiences.<\/jats:p>","DOI":"10.1145\/3351267","type":"journal-article","created":{"date-parts":[[2019,9,10]],"date-time":"2019-09-10T15:58:26Z","timestamp":1568131106000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":26,"title":["FlexTouch"],"prefix":"10.1145","volume":"3","author":[{"given":"Yuntao","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]},{"given":"Jianyu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]},{"given":"Hanchuan","family":"Li","sequence":"additional","affiliation":[{"name":"Microsoft, One Microsoft Way, Redmond, WA, USA"}]},{"given":"Tengxiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Computing Technology, Chinese Academy of Sciences, Zhongguancun, Beijing, China"}]},{"given":"Minxuan","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]},{"given":"Zhuolin","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]},{"given":"Chun","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]},{"given":"Shwetak","family":"Patel","sequence":"additional","affiliation":[{"name":"University of Washington, Seattle, WA, USA"}]},{"given":"Yuanchun","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology; Key Laboratory of Pervasive Computing, Ministry of Education; Global Innovation Exchange Institute (GIX); Tsinghua University, Beijing, China"}]}],"member":"320","published-online":{"date-parts":[[2019,9,9]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/2207676.2208371"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/502716.502729"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/3241539.3241546"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2556288.2557173"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/3025453.3025808"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/2817721.2817722"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/1449715.1449747"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702518"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/3173574.3174095"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2815585.2817776"},{"key":"e_1_2_2_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702500"},{"key":"e_1_2_2_12_1","doi-asserted-by":"publisher","DOI":"10.1145\/2984751.2985700"},{"key":"e_1_2_2_13_1","doi-asserted-by":"publisher","DOI":"10.1145\/2493432.2493486"},{"key":"e_1_2_2_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/3173574.3173934"},{"key":"e_1_2_2_15_1","doi-asserted-by":"publisher","DOI":"10.1145\/2501988.2502048"},{"key":"e_1_2_2_16_1","doi-asserted-by":"publisher","DOI":"10.1145\/2807442.2807494"},{"key":"e_1_2_2_17_1","doi-asserted-by":"publisher","DOI":"10.1145\/2642918.2647413"},{"key":"e_1_2_2_18_1","doi-asserted-by":"publisher","DOI":"10.1145\/2501988.2501989"},{"key":"e_1_2_2_19_1","doi-asserted-by":"publisher","DOI":"10.1145\/2658779.2659101"},{"key":"e_1_2_2_20_1","doi-asserted-by":"publisher","DOI":"10.1145\/506443.506570"},{"key":"e_1_2_2_21_1","volume-title":"Ubicomp 2001: Ubiquitous Computing, Gregory D","author":"Pinhanez Claudio","unstructured":"Claudio Pinhanez . 2001.
